SATFACTS: Live Cinema Broadcast Transmission Information 
Porque subtitulan los espectáculos? Why the spectacles are not subtitled? Please, do it
Hello and thank you for getting in touch. Many of the Opera are subtitled as the librettos were translated many years ago and are freely available. Many of the Plays from e.g. NT Live are new (compared with opera) productions and have not been translated. The costs of doing so are usually uneconomic for the number of viewers. I hope the lack of subtitles does not detract too much from your enjoyment.
